Feature: #69543 - Introduced $GLOBALS[‘TYPO3_CONF_VARS’][‘SYS’][‘mediafile_ext’]

See Issue #69543

Description

Now we got the RendererRegistry with the VideoTagRenderer , AudioTagRenderer and MediaViewHelper in the core we needed also a way to define a list of file extensions of the files that can be handled by these. This list can then be used in the TCA for allowing sys_file_references to these files.

// Comma list of file extensions perceived as media files by TYPO3.
// Lowercase and no spaces between
$GLOBALS['TYPO3_CONF_VARS']['SYS']['mediafile_ext'] = 'gif,jpg,jpeg,bmp,png,pdf,svg,ai,mov,avi';

TCA example:

'media' => array(
        'label' => 'LLL:EXT:lang/locallang_general.xlf:LGL.media',
        'config' => \TYPO3\CMS\Core\Utility\ExtensionManagementUtility::getFileFieldTCAConfig('media', array(
                'foreign_types' => array(
                        '0' => array(
                                'showitem' => '
                                        --palette--;LLL:EXT:lang/locallang_tca.xlf:sys_file_reference.imageoverlayPalette;imageoverlayPalette,
                                        --palette--;;filePalette'
                        ),
                        \TYPO3\CMS\Core\Resource\File::FILETYPE_TEXT => array(
                                'showitem' => '
                                        --palette--;LLL:EXT:lang/locallang_tca.xlf:sys_file_reference.imageoverlayPalette;imageoverlayPalette,

                        ),
                        \TYPO3\CMS\Core\Resource\File::FILETYPE_IMAGE => array(

                )
        ), $GLOBALS['TYPO3_CONF_VARS']['SYS']['mediafile_ext'])
),

Extending this list:

If you want to extend this list you can add the desired extension name to list in the ext_localconf.php of your extension.

$GLOBALS['TYPO3_CONF_VARS']['SYS']['mediafile_ext'] .= ',myext';
